To-all whom t may coneem:

Be it known that I, GEORGE lV. BOLL, citizen of the United States, residing at ltv'louiit Hope, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Storage-Bins; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the-art to which it appertains to make and use the'same.

My invention relates to improvements in storage receptacles or bins adapted for holding grain etc., and has to do particularly with the construction of the roofs of such bins.

It has for its object to provide a roof for a granary or storage bin of the knock-down type which is simple in construction and very strong and durable.

Further objects of the invention will appear from the following description.

The invention consists in the featur of construction and combinations of parts hereinafter described and specified in the claims.

Iii the accompanying drawings, illustrating the preferred embodiment of my invention: Figure 1 is a broken elevation of a bin constructed in accordance with my invention, partly in central section. Fig. 2 is a top plan view. Fig. 8 is an under plan view of the roof. F ig.l 4 is a broken sectional View ou the line y-y of Fig. 2. Fig. 5 is a detail view of one of the roof beams. 6 is a broken plan view of the liatcliway in the roof. Fig. 7 is an under plan View of the hatch, and Fig. 8 is a broken detailed view showing a modified construction of tubular support at the center of the roof.

'Referring more particularly to the drawings, 1 designates the body of the bin, .the

wall of which is preferably of circular lor cylindrical form and is composed of a number of superposed circular sections, the numher and diameter of said sections being governed by the desired capacity of the ycom'y pleted bin. As the specific construction of the body of the bin forms the subject matter of my copending application Serial No. 409,554, filed January 6, 1908, do not deem it necessary to describe it herein detail.

The roof 2 is supported upon a plurality of radially arranged roof beams or rafters il having horizontal base fianges 4 and vertical flanges 5. Each of said roof beams is also provided with depending lugs and 7 ,Cap

respectively at its opposite ends. These lugs` are formed by cutting and bending dawn the extremities of the horizontal flange 4. The inner lug 6 is bolted or otherwise secured as at 8 to a tubular support 9 arranged at the center or apex of the ioof. The outer lug is secured at 10 to an angle iron band l1 which is in turn fastened to the upper edge of the body or walls of the bin. The outer end of the vertical flange 5 extends overeind Patenteunug. 24, ieee.

rests upon said angle iron 11 which serves to strengthen the top of the' bin against the pressure of the grain from the inside. lt will he noted that the lugs 6 and 7, are respectively arranged at acute and obtuse an gles tothe horizontal ianges in order to ive the proper itch tothe roof when in position.

The roo proper comprises plates 12 proferably made of sheet metal, every alternate edges and the others being provided with inverted U-shaped flanges 14 at their lateral edges. The sections having the vertical flanges are placed between tlie'beanis 31, with zontal or base flange of one of said beams and said vertical flanges registering with the vertical flanges 5 of the beams. The plates carrying the inverted lll-shaped flanges are then positioned with said anges extending over the vertical flanges of the roof beams and other. plates thereby forming water tight joints. The plates and beams .are fastened together by means of bolts 15 passed therethrough. The inner ends of the roof plates are vcut to conform to the outer surface of the tubular support 9. A. conical piece 16 to shield the opening of said tubu ai' support is arranged on the apex of the roof and is supported by arms 17 carryL ing clips 18 engaging opposite flanges of the roof plates and fastened thereto by means of bolts 19.

In one of the roof plates there is formed a filling hatchway 20 which is preferably pointed at.its up er end. Around the sides and ends of said hatchway are fastened angle irons 21 having lateral flanges 22. The upper part of the lateral flanges on ,the

.75 plate having vertical flanges 13 at its lateral '80 one edge of each plate resting on the horiioo sides of the hatchway are cut away at 23.

When it is desired to remove the hatch 24 which has flanges 25 corresponding to and adapted to engage the flanges around the hatchway, it is only necessary to move said hatch upwardly until the flanges 25 clear the flanges 22 on the sides of the opening l A horizontal of thel beam which, of course, gives the pitch after which the hatch can be raised. It will be observed that the upper pointed ends of the hatch and hatchway are protected fromv the roof. Said Ventilating pipe 1s secured to the bottom of the bin in any suitable manner and isincased in a line mesh wire screen 27. to prevent the grain from entering the pipe 26 by means of the perforations therein. ipe section 28 communicates with the Ventilating pipe through the bottom' of the bin and also with the outside air. This insures rfect circulation of air throu h the bin and revents the grain store therein -from mo ding. i

In Fig. 8, I have illustrated a modified construction of tubular su port 29 at the center of the roof. Said tubular support is provided with a flange 30 around its lower edge to su port the inner ends of the beams 31 which o not have any dependin lugs at said ends but are sured to said bolts 32. The vup r face of said flange is preferably bevele to conform to the incline to the roof.

I claim:

1. The combination, with a wall, of a roof beam having a horizontal flange anda vertical flange, one extremity of said horizontal flange being cut and bent to form a lug se.-`

cured to the upper ed of said wall, the corresponding end of sald vertical flan e extendin over and resting upon the wal and roof ates supported on said beam.

2. Bhe combination, with a wall, `of a roof ange by beam having ya horizontal, liange and a vertical flange, one extremity of said horizontal flange being cut and bent to form a lug secured to the upper edge of said wall, the corres onding end of said vertical flange exten ing over and resting uson said wall, a roof late supported at one e ge on the hori zontal-l) flange of said beam andV provided with an upstanding flanve registering with the vertical flange on said beam, and another roof plate having an inverted U-shaped flange at its edgel which extends over the vertical flange on the beam and the upstanding flange'on the other plate.

3. The combination, with a roof having a hatchway therein bounded on all but one side by bent pro'ecting anges, and a hatch having turned flanges on all but one side adapted to engage said lirst mentioned flanges, portions of the flanges at opposite sides of the hatchway being cut away to allow the hatch to be quickly removed.

4. The combination, with a tubular support arranged centrally of the roof and havin aflange around its lower edge, of radi-v GEORGE W. BOLL.
